Abstract

The use of coal as fuel for PLTU Tenayan Raya Pekanbaru produces waste in the form of fly ash and bottom ash. Fly ash has high silica and alumina content which has the potential to replace cement. The resulting fly ash is partly not utilized and is piled up in the ash disposal area and has the potential to cause water and soil pollution. The increasing use of coal, the environmental burden will be heavier and needs to be anticipated by finding optimal utilization of coal fly ash waste. Based on the description above, community service activities have been carried out in Pematang Kapau Village, Tenayan Raya Pekanbaru District in the form of socialization and training on the use of fly ash waste as a material for making geopolymer paving blocks without using portland cement which has been used in the process of making paving blocks and other building materials. From the results of the above training activities obtained geopolymer paving blocks with specifications rectangular shape with a length of 21 cm, width 10 cm and height 8 cm, gray color and the test results obtained compressive strength of 40.87 MPa into SNI quality standard A.

Abstract

This study aims to find out: the effectiveness of character education models in improving social skills for transvestites in Yogyakarta Special Region. This research uses Research and Development method which consists of four stages, namely: (1) preliminary stage, (2) the planning stage of character education models for transgender as the development of the initial product form, (3) the testing, evaluation and revision stages through practical learning improvement of social skills, and (4) implementation phase. The number of transsexuals who were sampled in the one-on-one trial in 2015 was 5 transvestites selected by purposive sampling. In the second year the trial was expanded to 1 management of Kebaya Shelter house and involved 22 transvestites. Whereas field operational trials were conducted on 32 transvestites in Kebaya and Iwayo. Data collection techniques use FGD techniques, questionnaires, interviews, observation, and documentation techniques. Data validity uses expert validation, while the validity of qualitative data with source triangulation techniques, theory and methods. Quantitative data analysis with descriptive analysis techniques and qualitative data with interactive models. The results showed that: Field operational trials of 32 transvestites, it can be seen that there was an increase in transvestites' social skills after training the character education model of SPS models for waria. The pretest results showed a good average classification with a mean of 3.20. While the posttest results indicate an increase to a good classification with a mean of 3.58. Based on these data shows that all aspects that are considered good regarding social skills show a good and good classification.  Keywords: Problem Solving, social skills, of transvestites

Abstract

Availability of fossil fuels are depleting resulted in higher mining costs and selling prices to the public. In addition, the results of its combustion also releases GHG to the environment. One way to reduce the use of fossil fuels is produce bio-oil through pyrolysis technology. Ketapang rod is a huge potential used as feedstock for bio-oil production because its high cellulose content (41.80%). Synthesis of bio-oil from Ketapang stem begins with the process of size reduction of biomass and natural zeolite to -100+200 mesh size. Then, into the natural zeolite impregnated Ni and Mo to form the bimetallic catalyst NiMo/NZA. The catalyst is then activated through the stages of calcination, oxidation, and reduction. Pyrolysis process is done by varying the weight percentage of catalyst to biomass, ie: 1.5%, 2%, 2.5%, and 3% w/w. In addition, the catalytic pyrolysis process is carried 3% NZA only  and 3% NiMo/NZA were activated by calcination process alone. The highest yield was obtained on the use of catalysts NiMo/NZA perfect activated which amounted to 91.05%. From physics analysis performed on the bio-oil obtained: density of 0.91 g/ml, viscosity 10.839 cSt, acid number 46.954 mg NaOH/g sample, flash point 52oC, and the heating value 42.66 MJ/Kg. The figures are included in the range of physical characteristics of diesel-oil. Five (5) the dominant compound results of chemical analysis by GC-MS of the bio-oil from Ketapang rod by using a catalyst NiMo/NZA 3% by weight are: 3,4,4-trimethyl-2-nonene (10.29%), isobutylene (8.84%), 2,2-dimethyl-butane (8.05%), 3,4,4-trimethyl-2-pentene (5.76%), and 2-methyl-1-heptene (5.26%).  Keywords: Bio-oil, Pyrolysis, and Catalyst NiMo/NZA

Abstract

Fuel is a very important energy. The increase need fuel and diminishing avaibility of fossil fuel. It is also increasing awareness to find alternative energy technology. one of thesealternatives energy is bio-oil. bio-oil is a fuel, organic liquid produced by pyrolysis process. Pyrolysis of biomass a palm midrib. in a palm tree produces 40-50 midrib/tree/year so thatone hectare of palm can produce 6400 to 7500 midrib/year. manufacture of bio-oil with pyrolysis process can be done using Ni-Mo catalyst/Clay. This study aims to find the performance of the catalyst Ni-Mo/Clay Cengar (0%, 1%, 3% and 5% w / w biomass) against yeild bio-oil produced and characterize physical and chemical properties. pyrolysis palm midrib -40+60 mesh size of 50 grams, 0.5 grams of catalyst in 500 ml silinap performed at a temperature of 330 oC. The development Ni-Mo metal on clay cengar shown to affect the yield bio-oil is obtained, while the results obtained yield at 0%, 1%, 3% and 5%, respectively, 49.40%, 58.87%, 53.11% and 49.92%. bio-oil yield results that the maximum 58.87% obtained on treatment using a metal carrier Ni-Mo/clay cengar 1%. characterizationbiooil physical properties of of Ni-Mo/clay impurity 1% w/w has physical characteristics that density 0.9466 g/ml, 10.87 cSt viscosity, flash point 55C, and acid number 0.0751 g NaOH /g sample. based on the results of the analysis of the chemical components bio-oil is best obtained in the treatment bio-oil Ni-Mo/clay impurity 3% w/w bio-oil contains alcohol 7.35%, 0.35% phenol and other compounds 6.72% hydrocracking.Keyword : Bio-oil, a palm midrib, Pyrolysis, Ni.Mo/Clay Cengar
